Project Bulletin 7

The orphanage at Namisu has its own fields and gardens attached to it. In these are grown crops that are used to feed the children. In the past few months in one of the greenhouses trials have been taking place to test out the soil from the soil donuts.

Biofertiliser produced by the Flexigester was passed through Pasteu tubes to deactivate any pathogens in the liquid before being poured onto a soil donut. The soil donuts, which contained the dirt soil removed from the trench when the Flexigester was installed, captured the nutrients out of the digestate. This nutrient-enriched soil was then put into smaller bags and a tomato plant was planted in each. Some tomato plants were grown in soil straight from the donuts whereas other had additional fertiliser added to the donut soil. The results can be seen in the photographs.

Angus the General Manager of the orphanage said “Those growing totally on donut soil are doing well, those which had additional are growing exceptionally well. So that although there is a fertilizer benefit, the trials equally prove that those without fertilizer will do pretty well too on the soil enriched only with biofertilizer from the Flexigester”.
